I am curious why some run premium when their small engines only require regular gas?
Simple. Most premium fuel is also ethanol free gasoline.
In bigger engines the benefits go far beyond not having gummed up carb’s, the net cost per mile is lower running premium gas than regular gas.
The increased fuel mileage exceeds the increased cost per gallon.
